Included in the package are the switching controller, power switches, inductor and all support ponents. Operating over an input voltage range of 3.6V to 58V, the LTM8050 supports an output voltage range of 0.8V to 24V and a switching frequency range of 100k Hz to 2.4MHz, each set by a single resistor. Only the bulk input and output filter capacitors are needed to finish the design. The LTM8050 is packaged in a 9mm × 15mm × 4.92mm ball grid array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8050 is available with Sn Pb (BGA) or Ro HS pliant terminal finish.
